COOKING-STOVE.

Specification of Letters Patent.

Application filed September 8, 1914, Serial No. 860,507. Renewed June 3,1916. Serial No. 181,644.

To all whom it may concern:

Be it known that I, ARTHUR lV. WALKER, a citizen of the United States,residing at ltlalden, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements inCooking-Stoves, of which the following is a specification.

This invention relates tothose parts of cooking stoves which are usedfor broiling, and is particularly applicable to cooking stoves having abaking oven which is heated by means of one or more burners locatedbeneath it and adapted to be used for broiling articles of foodsupported at a suitable distance below them, the term burners as iercinused being intended to include gas and liquid-fuel burners and theirfunctional equivalents, such as electric heating devices. The principalobjects of my invention are to economize space by doing away with thefixed broiling oven commonly employed heretofore, to provide simple andpractical means whereby the articles to be broiled may be held at anydesired distance below the burners while the broiling operation is goingon, and to facilitate the operations of introducing and removing thearticles and attending to the same while being broiled, and with theseand other objects in view I employ, in connection with one or morebroiling burners, a broiler support so combined with the burners that itcan be moved upward or downward with respect to the same and ismaintained in substantially horizontal position during such movements,with provisions whereby the broiler may be located at various distancesfrom the burners, according to the degree of heat required for broiling.Various means may be employed for combining the broiler support with theburners and providing for its upward and downward movements insubstantially horizontal position, but preferably the support ispivotally suspended on bangers so arranged that when the support movesdownward it also moves forward, since in such case the introduction,manipulation and removal of the articles to be broiled are facilitated.

In the accompanying drawings illustrating my invention:

Figure 1 is a front elevation with parts broken away, showing a portionof a gas stove containing my improvements in their preferred form;

Fig. 9. is a side elevation, partly in section, of the parts shown inFig. 1;

Fig. 3 is a side elevation showing certain details hereinafterdescribed;

Figs. 4: and 5 are views similar to Fig. 2 but illustrating somewhatmodified constructions;

Figs. 6 and 7 are detail views illustrating modified forms of thebroiler support;

Figs. 8 and 9 are sectional views showing respectively the supports ofFigs. 6 and 7 combined with the baking oven; and

F 1g. 10 is a fragmentary side elevation showing a locking devicehereinafter described.

Beferring first to Figs. 1, 2 and 3, 2 indicates a support or base forthe parts located above it, 3 indicates a rear wall extending verticallytherefrom, A indicates a vertical side wall extending forward from thewall 3 at one end of the suppor 2, and 5 indicates a casing which iscarried by the parts 8 and A at a suitable elevation above the support 2and constitutes the outer or inclosing casing of a baking oven 6. Aspace 7 is left between the oven 6 and the outer casing 5, to serve as aflue, and said outer casing 5 is provided with the usual door 8 forclosing the front of the oven and with one or more gas burners 9extending inward beneath the bottom of the oven. These burners arelocated directly over an opening 10 in the bottom of the casing 5 andare supplied with gas from a pipe 11, cocks 12 being provided forcontrolling the supply to the respective burners. As described thus farthe parts may be of any usual or suitable construction and arrangement,the particular construction illustrated being such as is commonlyemployed in gas-heated stoves of the cabinet type. The support 2 mayconsist of the main top portion or table of such a stove, or it mayconsist of the top of an ordinary cooking stove or range using coal asthe fuel.

The form of broiler support illustrated in Figs. 1, 2 and 3 consists ofa transverselyextending plate 13 pivotally suspended on two U-shapedhangers 14: and 15, the upper ends of which are provided withlaterallyextending pivots 16 located in suitable horizontal bearingsformed in the sides of the downwardly-extending lower portion 17 of thecasing 5. The plate 13 is thus adapted to move upward and downward inthe uninclosed and otherwise unoccupied space below the casing 5, and onthis plate when lowered any usual or suitable form of broiler may besupported, the side edges of the plate being preferably turned upward asat 18 to serve as partial side walls for the space containing thebroiler, according to the height of said side edges, thereby providingWind shields which cut off or minimize the effect of drafts of air whenthe broiling operation is in progress. Preferably, also, theconstruction is such that said plate 13 re mains horizontal in allpositions, but this is not essential so long as it is so nearlyhorizontal when lowered that the broiler will rest upon it.

The hangers 14 and 15 are so proportioned and arranged that when theplate 13 is moved upward into the position shown in Fig. 1, in which itsside edges 18 embrace the side walls of the portion 17 of the easing 5,said plate closes the open bottom of the casing and thus prevents theheat of the burners 9 from being felt below the oven when said burnersare used for baking only,

but when said plate 13 is lowered into the position shown in dottedlines in Fig. 2 it also moves forward somewhat beyond the front of theoven, thereby making it conveniently accessible for the introduction andremoval of the broiler and its contents. During the operation ofbroiling, however, the plate 13 is caused to occupy a suitableintermediate position in which the article to be broiled will be-broughtmore directly beneath and closer to the burners 9, and for the purposeof holding said plate in any desired intermediate position I have shownin Figs. 1, 2 and 3 an arrangement consisting of a slide 19 locatedoutside of the hangers 14; on one side of the oven and mounted to slideforward and backward on a bracket 20 secured to the casing 5. The top ofthe slide 19 is received between and guided by two downwardly-projectingribs 21'formed on the under side of said casing.

To said slide 19 is secured a forwardly-projecting rod 22 having ahandle at its front end, by means of which the slide may be movedforward or backward, and a laterally-projecting finger 2 1 is carried bythe slide in position to engage the under side of the adjacentsuspending arm of the front hanger 14 in such manner that when saidslide is pushed backward the finger 23 will act as a cam on the underside of said arm and elevate the plate 13. By giving said hanger arm asuitable curvature, as shown in Figs. 2 and 3, the arrangement will berendered self-locking in any position suitable for broiling, since thepressure on the finger 24: will be exerted in a direction so nearlydownward that it will be ineffective to move the slide 19 against itsfrictional resistance. Whenever the handle 23 is pulled forward,however, it will be accompanied by a downward movement of the plate 13,which will remain in whatever position it occupies when the forwardmovement of said handle is stopped.

Instead of employing the arrangement shown in Figs. 1, 2 and 3 forholding the broiler support 13 in a given position the arrangement shownin Fig. t may be adopted, in which said support is carried by hangers14-" having straight suspending arms, one of said arms being providedwith an extension 25 which projects upwardly above its supporting pivotand is pivotally connected to the rear end of an arm 26 extendingforwardly along the side of the casing 5. This arm 26 is pr'ovided atits outer end with a handle 27 and on its under side with a series ofnotches 28, any one of which may be caused to receive a locking pin 29carried by the casing 5, according to the desired position of thesupport 13. Lateral movements of the arm 26 are prevented by a guide 30secured to the casing 5, with its lower end overlapping the outer sideof said arm 26, sufficient space being provided to permit such a liftingmovement of the arm as is necessary to disengage the same from thelocking pin 29. Still another arrangement for the same purpose is shownin Fig. 5, in which the slide 19 and its finger 24 are retained but thesuspending arms of the front hanger 1 1 are straight, the slide 19 beingpositively locked in any desired position by providing the under side ofits operating rod 22 with a series of notches 31, any one of which isadapted to receive" the upper edge of a guiding flange 32 at the frontof the casing 5.

Instead. of providing a locking device for holding the broiler supportat a given elevation, said support may be arranged to drop to itslowermost position when released, in which case the broiler will beadjustably supported thereon. As an example of this, Fig. 6 illustratesa construction in which. the broiler support'comprises a plate 13supported by hangers consisting of four pivotal links 33, said plate being provided with upwardly-extending side plates 31 having on theirinner faces a number of opposed ledges 35, on'any pair of which abroiling pan may be supported. When this construction is employed thebearings for the pivot pins 16 at the upper ends of the links 33 arepreferably located close to the bottom of the lower portion 17 of thecasing 5, and the side plates 34 are set inward from the links to suchan extent as to cause them to pass upward within said lower portion ofthe casing when the plate 13 is moved into its uppermost position,as-shown in Fig. 8.

A somewhat similar arrangement is shown in Fig. 7, in which the broilersupport 13" has its suspending links 83 pivoted to lugs 36 extendingupward from-the top of said support, the broiling pan (shown in dottedlines at 37) being adjustably supported as to height by means of opposedpins 88 projecting inward from said links 33. This form of broilersupport is preferably combined with the oven by mounting the upper endsof the links 33 on pivot pins 16 extending inward fromdownwardly-extending lugs 39 carried by the casing 5, as shown in Fig.9, and is represented as having the form of a rectangular frame, beingprovided in such case with a removable bottom plate 40 (Fig. 9) to serveas a closure for the opening in the bottom of the casing 5 when thesupport is elevated.

The broiler supports 13 and 13', in the absence of operating connectionssuch as have been described in connection with the support 13, may beheld in elevated position byany suitable means, such as a catch 4L1pivoted to the front of the oven casing and adapted to engage the underside of the support as shown in Fig. 10.

It will be seen that in each of the various constructions abovedescribed a saving of space is effected by reason of the fact that whenthe parts employed for broiling are not in use for that purpose they arecompactly folded or collapsed beneath the baking oven, thus leaving thespace below the latter available for other purposes. As a result of thisthe baking oven may, if desired, be located at a lower elevation thanwould be practicable if it had a fixed broiling oven beneath it, andthis is particularly advantageous when the baking oven is located abovethe main top portion of a coal-heated stove or a gas stove of thecabinet type, since the parts used for baking and broiling are thus mademore conveniently accessible for use. It is to be observed, however,that my broiler support may be employed if desired in connection withbroiling burners located elsewhere than below the bottom of a bakingoven, and it will be evident that various modifications other than thoseabove described may be made in the construction and arrangement of saidsupport and associated parts without departing from my invention.
